Calling all CCR manufacturers!

I know plenty rebreather dives that haven't registered on Rebreather World.

Obviously, only x % of Rebreather divers are on Rebreather World
But it’s safe to assume that x is constant for Meg, Boris , rEVO divers
So having a nice manufacturer like Paul who gave the exact number of rEVO in use we can then have another way of ESTIMATING the number of units

The rEVO example is a good one, there are 98 members claiming that they currently own a rEVO (keep in mind that’s it a new unit so few have been sold or hang in the garage) that is very reasonable in relation to the 124 sold as stated by paul

There can't be that big a question mark ... we already have accurate figures "to within 10%", remember? In any case we automatically cut actual sold numbers by 50% anyway. Evidently we know the others are garage decorations.


Of course, I stipulate that you are the model of objective debate.


Yes! Hitting those wicked manufacturers hard and fast is both fun and makes us look "objective" and "avid supporters of safety." Let's all kick those wicked, wicked people who delivery to us what we want (when will it be available?). Then we can despise them for allowing us to use the stuff we clamor to get (all eCCRs are crap, remember?). Who cares that we jumped at the chance to purchase what was the latest, coolest gear available to us -- if I screw up I have an enemy to attack and experts ready to help my attorney make me look reasonable in court.


Hey, Mike, my post was a light-hearted reply to Gill's open letter. My post was hypothetical ... what I thought I'd say "if I were a manufacturer". I'm not. You're shadow boxing. Go out and find another 'enemy'.

not a big secret: effectively today, best estimate of :
actually IN USE units: 124 rEvo's ( all mCCR, exept 4 :-)

then +/- 10 not in use (stolen, lost, truck drove over it, decoration of the garage..)
then +/- 10 supplied but not yet in use (waiting for training)

See the notes.

The Meg was a difficult one to treat fairly, but I did my best. The problem comes from the Meg accidents so far seem to all relate to earlier units sold, and the ramp over the past year is so large as to greatly distort the figures for the Meg anyway.

If you have 654 units out now (including double accounts on Rebreather World, and some who trained and then sold their unit etc), the mean since introduction is half that with linear ramp. We know the Meg ramp was by no means linear, so the mean (i.e. the median number in service per year) is a lot lower. By taking the first 300 units as the ramp, we appear to get an accurate statistic. We have to wait a year to see how the next 354 units go.

On Paul, thanks: my figures on your sales were a good 9 months old. Update will be out within minutes! Green also.

There are some units on the list for which there is appears to be no option on Rebreather World: Voyager, Submatix. Any instructors like to comment on these? Can Rebreather World add Voyagers and Submatixes to the option list for the future as simple means for people to double check?

I also gave the Azimuth the benefit of the doubt by putting every single unit on Rebreather World as a unit in active use. The figures for the Azimuth are so bad, it still stands out. The real figure of Azimuths in regular use is a lot less than this (i.e. I believe it is my original number).

... So a ground breaking idea to the mods: Delete from all the profiles the "unit currently owned"
Send a PM to all users to update their profile. Obviously only the current, active members will respond and we will end up with more accurate number of "unit currently owned"

no know accidents until today
